SEPARABLE BUTTON.

SPECIFICATION forming part of Letters Patent No. 574,265, dated December 29, 1896.

Application filed March 20, 1888, Serial No. 267,866. (No model.)

To MLM/hom it may concern,.-

Beit known that I, EUGENE PRINGLE,a citizen of the United States, residing at Gloversville, in the county of Fulton and State of New York, have invented certain new and useful Improvements in Separable Buttons, of which the following is a specification.

My invention relates to improvements in separable buttons; and it consists of the devices, parts, and elements and combinations of devices, parts, and elements hereinafter particularly described, and specifically set forth in the claims.

The objects of my invention are to provide in a button-head of a separable button a studrec-eiving tube, which will also constitute the fastening-eyelet of thebutton-head, and will operate in connection with a stud-engaging piece to hold the stud and receive the lateral strain on the same; also to provide in a stud of the separable button an elastic compressible engaging piece which will coact with the stud-engaging piece in the button-head to hold the stud connected with the same;

. also to provide in a stud an elastic compressible engaging ring, which will be annular to the stud-post, with provision for compression for passage through a contracted stud-receiving opening in the button-head, and, inally, to provide specic combinations of devices, parts, and elements by which my improvements are embodied in practical form in separable buttons.

I attain these objects by the means illustrated in the accompanying drawings, forming a part of this specication, in Which- Figure lis a sectional elevation of the parts of the separable button connected together and secured to the material. Fig. 2 is a sectional view of the outer shell of the buttonhead. Fig. 3 is a sectional view of the piece forming the stud-receiving tube and eyelet. Fig. 4 is a sectional View of the upper side clamping-piece of the button-head. Fig. 5 is a sectional view of the under side clampingpiece of the head. Fig. 6 is a sectional view of the stud-engaging plate. Fig. 7 is a sectional vieW of the outer shell and the upper side clamping-piece secured to a fasteningeyelet of modified form. Fig. 8 is a sectional view of a button-head having some of its parts of modified form. Fig. 9 is a sectional elevation of the parts composing the lower clamping` portion of the button-head and a fastening-eyelet and tool for expanding and clenchng the tube of the latter. Fig. l0 is a sectional view of the parts composing the upper half portion of the button-head, an inverted fastening-eyelet, and tool for turning` and clenching the tube end of said eyelet. Fig. ll is a sectional elevation of the stud embodying a part of the improvements in this invention. Fig. l2 is a sectional View of the same from above. Fig. 13 is a sectional view of an elastic compressible engaging ring of shell form. Fig. le is a sectional view of the same made with a solid form. Fig. l5 is a view of the same from above.

The same letters of reference refer to similar parts throughout the several views.

In the drawings, A is the top or outer shell of the button-head. B is the upper side clamping-piece, and C is 'the fastening-eyelet, having its top flange c bearing against the top shell and its tube portion c in the central opening b of piece B. This tube portion c' of eyelet O has made with it an annular shoulder c2, which seats on the upper side of piece B at the margin edge of the opening b in the same.

D is the lower side clamping-piece, which has in it a central opening and a rim-flange d around the saine, on which the tube portion of the eyelet C is clenched.

E is the stud-holding plate, shown to be arranged against the lower side of the clamping-piece D and secured to the same by its rim-ange being clenched on the said clamping-piece; yet, if preferred, a flange made with piece D and clenched on plate can be employed with the saine result. This plate E has in it the stud-receiving opening-c, having its dia-meter a little less than that of the base of the tube of the fastening-eyelet C, so that the border edge of said openingein plate E will project toa small distance inwardly past the line of the bore of the said eyelet for engagement with the catching part of a coacting stud.

In Figs. 3, 7, and 9 the lower end portion IGCI ci of the clenching tube portion c of the fastening-eyelet C is'shown to be contracted or curved inwardly.

In Fig. 9 is shown an anvil portion 15 of a suitable tool, by means of which this inwardly-curved portion c4 of the tube of the eyelet will be turned outwardly, so as to clench on the inner side of the rim-flange (Z of piece D when the said eyelet and piece are crowded together, as shown by full lines in Fig. l.

In Fig. 8 the fastening-eyelet C is shown to be used inverted and as being made without any shoulder and having its {iange forming the means for clamping the lower side oi' the material, while its tube is made to clench an upper end of the internal flange b. In Figs. 8 and lO the shell A' is shown to have in it the central perforation a, and in Fig. l0 is shown the anvil portion T, applied to said perforation to turn the clenchiug end c4 of the eyelet C when the latter and the button-head are forced together, as shown in Fig. 8.

F, Figs. l, ll, and 12, is the stud, which consists of the stud-post f, stud-head f', base fi, and the compression catching-piece F between the said postfand head f' and annular to the neel; f3, as shown in said figures. The compression catching-piece F is shown in Figs. l, ll, and l2 to be circular in form and having its central opening m to be a little greater than the diameter of the neck f3, and y in Figs. l2 and l5 this catching-piece F is i shown to have in one side of its body an opening n, which opening permits the body ot' this piece F to be compressed or contracted, so as to reduce its diameter to a diameter corresponding with that of the central opening e of the stud-engaging plate E for passage through the same from the lower side of said plate to within the lower end oi the tubes ol the eyelet, as shown in Fig. l.

In Figs. ll and 13 this compression catching-piece is shown to be made with a shell form, while in Fig. 14 it is shown to be solid, yet in all cases, whether the piece be of shell or solid form, it will be of elastic material, so that after compression or contraction it will spring outwardly to its normal size.

G, Fig. l, is the eyelet for fastening the stud to the material, and is shown to have its flange operating as a clamping-piece on the upper side of the material and its tube portion clenching over the central rim-flange 71. of the lower side clamping-piece II.

By my above-described improvements the button-head can be cheaply produced and readily fastened to the material, while its stud will be made to readily engage with the button-head and stronglyhold with the same, 6o

and by reason of the central opening of the catching-piece being a little larger than the diameter of the neck f3 the post and head portions of the stud can be drawn by the pull on the stud against the edge of the central opening in the catchingplate E and the wall of the eyelet C without aiecting the catchingpiece F. This stud, by omitting the pieces which attach it to the fabric, may be used with any suitable coacting head not attached to the fabric, or it may be secured to the fabric and used with any coacting head also secured to the fabric.

I am aware of patents to Shipman oi' Octo ber l2, 1886, No. 350,776; November il, 1880', and August 2l, 1888, and do not herein claim the invention therein shown.

Having described my invention, what I claim, and desire to secure by Letters Patent, is*

l. A button-head having an aperture in its cap, an engaging piece having an upturned flange upon its outer edge for connection with the cap, and a central upwardlyprojecting cylindrical portion, and afastening-eyeletpassed through the material and clenched over the upper edge of the cylindrical portion by a tool inserted in the aperture of the cap.

2. A button-head comprising a cap, a fastening-eyelet having a iiange at one end and connected to the cap, an engaging piece upon the opposite side of the material and having an aperture therein, i'or the insertion of a tool Afor turning a flange upon the opposite end of the eyelet for holding the head to the material, both of the ila-nges of the fastening eyelet being within the butt0nhead and concealed, substantially as described.

A button-head comprising a cap or shell, a clampingpiece secured thereto and bearing underneath a shoulder or projection formed upon the fastening-eyelet, for securing the head to the material, substantially z s described.

4. A stud for a separable button consisting of a post having an annular recess, a hollow, split, resilient ring within the recess, and a fastening-eyelet for holding the stud to the material substantially as described.

5. A stud for a separable button comprising a base, having an annular oiiset or shoulder, a head-piece connected thereto, and forming an annularI recess, and a resilient ring in the recess, substantially as described.
